Barry Mazur as an Applied Mathematician
Mathematicians are sometimes asked to help ‘outsiders’with applied problems. I'll report three of Barry's deviations in this direction. The first is about shuffling cards (OK, OK and random walk on finite groups of Lie type). The second is about wandering around on the streets of Paris (OK and random walk with reinforcement and the sigma model). The third is about Tomography (OK there IS an elliptic curve).
